What's going on with my skin right now?

My skin looks dry, dull, or rough, or it's losing its firmness and bounce

Collagen
Supported by controlled trials (Evidence grade A · No traditional record)
Clinically supports elasticity and hydration
Why this matches
If your skin feels less firm or is losing moisture, collagen peptides directly target the structural proteins that keep skin plump and resilient.
Why try it
Backed by a meta-analysis of human trials in which collagen supplementation significantly reduced wrinkles and improved skin hydration compared with placebo.
Dose or use
5–10 g daily, typically as a powder in water or a smoothie
Time to results
Typically 4–8 weeks
Key study
Meta-Analysis (2025, PMID 41174715): Dietary interventions in skin ageing: a systematic review and meta-analysis — pooled human data showed collagen significantly reduced wrinkles and improved skin hydration versus placebo.
Caution
Choose marine or bovine sources based on dietary preference; consult a practitioner if pregnant.
Astaxanthin
Supported by controlled trials (Evidence grade A · No traditional record)
Meta-analysis supports skin moisture and elasticity
Why this matches
For dull, dry, or less firm skin, astaxanthin is a microalgae-derived carotenoid antioxidant that pooled human trials link to better skin moisture and elasticity.
Why try it
Backed by a meta-analysis of randomized human trials in which oral astaxanthin significantly improved skin moisture and elasticity versus placebo; it did not significantly reduce wrinkle depth, so think of it as support for suppleness rather than a wrinkle eraser.
Dose or use
4–12 mg daily with a meal containing fat
Time to results
Typically 4–8 weeks
Key study
Meta-Analysis (2021, PMID 34578794): Systematic Review and Meta-Analysis on the Effects of Astaxanthin on Human Skin Ageing — pooled RCTs found oral astaxanthin significantly restored skin moisture and improved elasticity versus placebo.
Caution
May cause skin to take on a slightly orange tint at high doses.
Evening Primrose Oil
Limited human trials so far· Most of the research is laboratory or animal work (Evidence grade C · No traditional record)
May support skin moisture and suppleness
Why this matches
Rich in GLA (gamma-linolenic acid), this oil is especially relevant for dry or maturing skin that needs barrier reinforcement.
Why try it
One randomized, double-blind trial found benefits for selected skin parameters, including hydration — but it was conducted in patients taking isotretinoin, so the findings may not generalize to everyone.
Dose or use
500–1000 mg daily with food
Time to results
Typically 4–8 weeks
Key study
RCT (2022, PMID 35889936): Effect of Evening Primrose Oil Supplementation on Selected Parameters of Skin Condition in a Group of Patients Treated with Isotretinoin — a randomized double-blind trial in an isotretinoin-treated population, not the general public.
Caution
May interact with blood-thinning medications; avoid in epilepsy without medical supervision.
Vitamin A Deficiency
Not yet assessed· We have not reviewed the literature for this one (Evidence grade not assigned · Traditional use recognised)Recognised traditional use
A testable cause of dry, rough skin
Why this matches
If your skin looks dull, dry, or rough, low vitamin A is worth ruling out — dry skin is one of its hallmark early signs.
Why try it
Vitamin A is central to healthy skin cell turnover, so identifying and correcting a deficiency tackles a real underlying cause of persistent dryness rather than only its surface signs.
Dose or use
Ask your practitioner about checking your vitamin A status; correct through diet or supplementation if you're low.
Time to results
Typically 4–8 weeks after correcting a deficiency
Key study
Ungraded: drawn from the library's vitamin A deficiency guide, which names dry skin as a hallmark early sign; not a controlled-trial claim for this condition.
Caution
Vitamin A is fat-soluble and harmful in excess — don't take high doses without confirming a deficiency, and avoid supplementing in pregnancy without medical advice.
Omega-3 Fatty Acid Deficiency (EPA & DHA)
Not yet assessed· We have not reviewed the literature for this one (Evidence grade not assigned · Traditional use recognised)Recognised traditional use
A root-cause check for dry skin
Why this matches
If your skin stays dry or flaky, low omega-3s may be contributing — dry skin and eczema are among the first signs of an omega-3 deficiency.
Why try it
Omega-3s help hold moisture in the skin barrier and calm inflammation, so checking for a shortfall can reveal a correctable reason your skin feels dry.
Dose or use
Ask your practitioner about your omega-3 status; correct through oily fish, diet, or supplementation if you're low.
Time to results
Typically 4–8 weeks after correcting a deficiency
Key study
Ungraded: drawn from the library's omega-3 deficiency guide, which names dry skin and eczema as first-line signs; not a controlled-trial claim for this condition.
Caution
High-dose fish oil can thin the blood; check with your practitioner if you take blood thinners.
Biotin
Not yet assessed· We have not reviewed the literature for this one (Evidence grade not assigned · No traditional record)
Traditionally supports skin, hair, and nail structure
Why this matches
If you're low in biotin, correcting it can help; it's traditionally associated with maintaining healthy skin texture alongside hair and nail strength.
Why try it
Traditionally used to support the structural integrity of skin, particularly when dryness or flakiness is linked to nutritional gaps.
Dose or use
Follow product labeling; consult a healthcare practitioner.
Time to results
Typically 4–8 weeks
Key study
Traditionally used for this condition; this specific use has not been confirmed in controlled clinical trials.
Caution
High-dose biotin can interfere with some lab test results — inform your doctor before testing.

Nothing's wrong exactly — I want a brighter, even-toned glow and long-term skin resilience

Gotu Kola (Centella Asiatica)
Supported by smaller clinical studies· Centuries of traditional use (Evidence grade B · Traditional use long-standing)Long-standing traditional staple
RCT-supported for wrinkles and skin texture
Why this matches
If you want an overall glow and long-term resilience, gotu kola (Centella asiatica, the 'cica' herb) has human-trial support for reducing wrinkle depth and smoothing skin texture.
Why try it
Backed by a randomized, double-blind, placebo-controlled trial in which oral Centella asiatica extract significantly reduced wrinkle depth and surface roughness over 12 weeks versus placebo; it's long used in Ayurvedic and Chinese medicine to support skin repair and collagen.
Dose or use
Commonly taken as a standardized oral extract (around 200 mg/day, as used in the trial); also available topically.
Time to results
Typically 8–12 weeks
Key study
Randomized Controlled Trial (2026, PMID 42196964): A Randomized, Double-Blind, Placebo-Controlled Trial Assessing the Effects of Oral Centella asiatica Extract on Skin Aging-Related Parameters in Middle-Aged Korean Women — 200 mg/day for 12 weeks significantly reduced wrinkle depth and surface roughness versus placebo.
Caution
May not be suitable in pregnancy or with liver conditions; consult a practitioner before use.

My skin is touchy — it reacts to new products, weather, or stress

Postbiotic (heat-killed bacteria)
Limited human trials so far· Most of the research is laboratory or animal work (Evidence grade C · No traditional record)
Clinically studied for skin condition in women
Why this matches
For sensitive or reactive skin, this postbiotic works along the gut-skin axis to support overall skin condition — the kind of hydration and resilience that can help skin feel less easily thrown off.
Why try it
Supported by a randomized, double-blind, placebo-controlled study in healthy women showing improvements in general skin condition such as hydration and elasticity; its specific benefit for reactive, easily-irritated skin is a reasonable extension of that gut-skin support rather than something the study measured directly.
Dose or use
Follow product labeling; consult a healthcare practitioner.
Time to results

Zinc Deficiency
Not yet assessed· We have not reviewed the literature for this one (Evidence grade not assigned · Traditional use recognised)Recognised traditional use
A correctable driver of breakout-prone skin
Why this matches
If your skin is breaking out or slow to heal, low zinc could be part of the picture — zinc deficiency is known to show up as skin issues like rashes or acne and as delayed wound healing.
Why try it
Zinc is essential for skin repair and immune balance, so checking for and correcting a shortfall addresses a genuine, testable root cause rather than just the surface symptoms.
Dose or use
Ask your practitioner about checking your zinc status; correct through diet or supplementation if you're low.
Time to results
Typically 4–8 weeks after correcting a deficiency
Key study
Ungraded: drawn from the library's zinc deficiency guide, which lists skin issues such as rashes or acne and delayed wound healing among the signs of low zinc; not a controlled-trial claim for this condition.

Vitamin A Deficiency
Not yet assessed· We have not reviewed the literature for this one (Evidence grade not assigned · Traditional use recognised)Recognised traditional use
A testable cause of dry, rough skin
Why this matches
If your skin looks dull, dry, or rough, low vitamin A is worth ruling out — dry skin is one of its hallmark early signs.
Why try it
Vitamin A is central to healthy skin cell turnover, so identifying and correcting a deficiency tackles a real underlying cause of persistent dryness rather than only its surface signs.
Dose or use
Ask your practitioner about checking your vitamin A status; correct through diet or supplementation if you're low.
Time to results
Typically 4–8 weeks after correcting a deficiency
Key study
Ungraded: drawn from the library's vitamin A deficiency guide, which names dry skin as a hallmark early sign; not a controlled-trial claim for this condition.
Caution
Vitamin A is fat-soluble and harmful in excess — don't take high doses without confirming a deficiency, and avoid supplementing in pregnancy without medical advice.
Zinc Deficiency
Not yet assessed· We have not reviewed the literature for this one (Evidence grade not assigned · Traditional use recognised)Recognised traditional use

Typically 8–12 weeks
Key study
Randomized Controlled Trial (2026, PMID 42196964): A Randomized, Double-Blind, Placebo-Controlled Trial Assessing the Effects of Oral Centella asiatica Extract on Skin Aging-Related Parameters in Middle-Aged Korean Women — 200 mg/day for 12 weeks significantly reduced wrinkle depth and surface roughness versus placebo.
Caution
May not be suitable in pregnancy or with liver conditions; consult a practitioner before use.
Evening Primrose Oil
Limited human trials so far· Most of the research is laboratory or animal work (Evidence grade C · No traditional record)
May support skin moisture and suppleness
Why this matches
Rich in GLA (gamma-linolenic acid), this oil is especially relevant for dry or maturing skin that needs barrier reinforcement.
Why try it
One randomized, double-blind trial found benefits for selected skin parameters, including hydration — but it was conducted in patients taking isotretinoin, so the findings may not generalize to everyone.
Dose or use
500–1000 mg daily with food
Time to results
Typically 4–8 weeks
Key study
RCT (2022, PMID 35889936): Effect of Evening Primrose Oil Supplementation on Selected Parameters of Skin Condition in a Group of Patients Treated with Isotretinoin — a randomized double-blind trial in an isotretinoin-treated population, not the general public.
Caution
May interact with blood-thinning medications; avoid in epilepsy without medical supervision.
Postbiotic (heat-killed bacteria)
Limited human trials so far· Most of the research is laboratory or animal work (Evidence grade C · No traditional record)
Clinically studied for skin condition in women
Why this matches
For sensitive or reactive skin, this postbiotic works along the gut-skin axis to support overall skin condition — the kind of hydration and resilience that can help skin feel less easily thrown off.
Why try it
Supported by a randomized, double-blind, placebo-controlled study in healthy women showing improvements in general skin condition such as hydration and elasticity; its specific benefit for reactive, easily-irritated skin is a reasonable extension of that gut-skin support rather than something the study measured directly.
Dose or use
Follow product labeling; consult a healthcare practitioner.
Time to results
Typically 4–8 weeks
Key study
RCT (2025, PMID 41414786): Novel Application of Oral Postbiotics for Skin Condition in Healthy Middle-Aged Women: A Randomized, Double-Blind, and Placebo-Controlled Study.
Caution
Generally well tolerated; consult a practitioner if immunocompromised.

I'm drawn to time-tested herbs from Ayurvedic and East Asian traditions

Gotu Kola (Centella Asiatica)
Supported by smaller clinical studies· Centuries of traditional use (Evidence grade B · Traditional use long-standing)Long-standing traditional staple
RCT-supported for wrinkles and skin texture
Why this matches

Why try it
Backed by a randomized, double-blind, placebo-controlled trial in which oral Centella asiatica extract significantly reduced wrinkle depth and surface roughness over 12 weeks versus placebo; it's long used in Ayurvedic and Chinese medicine to support skin repair and collagen.
Dose or use
Commonly taken as a standardized oral extract (around 200 mg/day, as used in the trial); also available topically.
Time to results
Typically 8–12 weeks
Key study
Randomized Controlled Trial (2026, PMID 42196964): A Randomized, Double-Blind, Placebo-Controlled Trial Assessing the Effects of Oral Centella asiatica Extract on Skin Aging-Related Parameters in Middle-Aged Korean Women — 200 mg/day for 12 weeks significantly reduced wrinkle depth and surface roughness versus placebo.
Caution
May not be suitable in pregnancy or with liver conditions; consult a practitioner before use.
Boswellia
Not yet assessed· We have not reviewed the literature for this one (Evidence grade not assigned · Traditional use recognised)Recognised traditional use

I prefer hands-on care — acupressure points I can press or something I apply directly to my skin

LI11 (Quchi) - Large Intestine 11
Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional staple
Classic acupressure point for inflamed skin
Why this matches
If you're dealing with breakouts, redness, or irritation, LI11 is the point traditional Chinese medicine turns to first for hot, inflamed skin — it's classically used for eczema, acne, and other inflammatory skin conditions.
Why try it
In traditional practice LI11 is used to clear heat and calm inflammation, which is why it's a long-standing go-to for red, irritated, breakout-prone skin.

I want to find out if something's actually missing — test for deficiencies before adding anything

Vitamin A Deficiency
Not yet assessed· We have not reviewed the literature for this one (Evidence grade not assigned · Traditional use recognised)Recognised traditional use
A testable cause of dry, rough skin
Why this matches
If your skin looks dull, dry, or rough, low vitamin A is worth ruling out — dry skin is one of its hallmark early signs.
Why try it
Vitamin A is central to healthy skin cell turnover, so identifying and correcting a deficiency tackles a real underlying cause of persistent dryness rather than only its surface signs.
Dose or use
Ask your practitioner about checking your vitamin A status; correct through diet or supplementation if you're low.
Time to results
Typically 4–8 weeks after correcting a deficiency
Key study
Ungraded: drawn from the library's vitamin A deficiency guide, which names dry skin as a hallmark early sign; not a controlled-trial claim for this condition.
Caution
Vitamin A is fat-soluble and harmful in excess — don't take high doses without confirming a deficiency, and avoid supplementing in pregnancy without medical advice.
Zinc Deficiency
Not yet assessed· We have not reviewed the literature for this one (Evidence grade not assigned · Traditional use recognised)Recognised traditional use
A correctable driver of breakout-prone skin
Why this matches
If your skin is breaking out or slow to heal, low zinc could be part of the picture — zinc deficiency is known to show up as skin issues like rashes or acne and as delayed wound healing.
Why try it
Zinc is essential for skin repair and immune balance, so checking for and correcting a shortfall addresses a genuine, testable root cause rather than just the surface symptoms.
Dose or use
Ask your practitioner about checking your zinc status; correct through diet or supplementation if you're low.
Time to results
Typically 4–8 weeks after correcting a deficiency
Key study
Ungraded: drawn from the library's zinc deficiency guide, which lists skin issues such as rashes or acne and delayed wound healing among the signs of low zinc; not a controlled-trial claim for this condition.
Caution
Don't self-supplement high-dose zinc long-term — it can deplete copper; confirm a deficiency first.
Omega-3 Fatty Acid Deficiency (EPA & DHA)
Not yet assessed· We have not reviewed the literature for this one (Evidence grade not assigned · Traditional use recognised)Recognised traditional use
A root-cause check for dry skin
Why this matches
If your skin stays dry or flaky, low omega-3s may be contributing — dry skin and eczema are among the first signs of an omega-3 deficiency.
Why try it
Omega-3s help hold moisture in the skin barrier and calm inflammation, so checking for a shortfall can reveal a correctable reason your skin feels dry.
Dose or use
Ask your practitioner about your omega-3 status; correct through oily fish, diet, or supplementation if you're low.
Time to results
Typically 4–8 weeks after correcting a deficiency
Key study
Ungraded: drawn from the library's omega-3 deficiency guide, which names dry skin and eczema as first-line signs; not a controlled-trial claim for this condition.
Caution
High-dose fish oil can thin the blood; check with your practitioner if you take blood thinners.
Vitamin D
Not yet assessed· We have not reviewed the literature for this one (Evidence grade not assigned · No traditional record)
Check levels if skin is reactive or slow to heal
Why this matches
If you're low in Vitamin D, correcting it can help, as it plays a traditionally recognized role in skin immune balance and barrier integrity — especially relevant for reactive skin.
Why try it
Traditionally used to support the skin's immune function and barrier; deficiency is worth checking if your skin is persistently sensitive.
Dose or use
Follow product labeling; consult a healthcare practitioner.
Time to results
Typically 4–8 weeks
Key study
Traditionally used for this condition; this specific use has not been confirmed in controlled clinical trials.
Caution
Have your levels tested before supplementing; too much can be harmful.
